Seismic Shocks May Affect The Structural Stability Of Tailings Dams

, , , , , , , , , , , , , ,
Earthquakes are one of the main external causes behind tailings dams failures. Depending on the severity of an earthquake, cracks and breaches will either cause the dams to fail immediately, or affect the stability of the tailings structure. Seismic waves (elastic waves in the earth) play a large part in the extent of damage to…

The Inconvenient Truth of Tailings Dams Failures
